Flx n A TTORNEYS Pass d Julie 4,- 1935 UNlTED, STATE LAMINATED GLASS AND PROCESS OF ,MAKING THE SAME Earl L. Fix, New Kensington, and Brook J. Dennison, Tarentum, Pa., assignors to Duplate Corporation, a corporation of Delaware Application June 28, 1934, Serial No. 732,808 "6Claims. (01.49-81) I The invention relates to laminated glass which ordinarily consists of two sheets of glass cemented to the opposite sides of a sheet of cellulose plastic. Very considerable difficulty is encoun- 5 tered in cementing glass to cellulose acetate, ethyl cellulose, and to cellulose nitrate when the latter contains a high percentage high boiling plasticizer, and the invention is directed primarily to use with these plastics. The objects of the 10 invention are the provision of a process and cementing medium, (1) which can be used under ordinary compositing conditions, namely' at temperatures ranging from 240 degrees to 275 dcgrees E; (2) which will give a product that, under break tests, show results comparable'with those now secured when ordinary cellulose nitrate is laminated using gelatin as a cement; and (3) which shows good adhesion under continued exposure tests, such as are recognized and established in the art. A plate of laminated glass made in accordance with the invention is shown in the accompanying drawing, wherein:
The figure is a sectional view through the plate. In the drawing, I, l are sheets of glass; 2 is a sheet of cellulose plastic; and 3, 3 are layers of the cementing medium.
Briefly stated, the invention involves the use of a compound of boron, such as boric acid in I Grams Boric acid 7 0.25 Saturated solution silicic acid. E 100 In composition, the mixture is placed on the glass sheets in a thin film, preferably by spraying, and allowed to dry, after which the glass and a lamination is secured in the usual way by the application of heat and pressure, preferably by the hydraulic method of the Sherts and Hamill Patent No.'1,'781,084, the pressure employed is the final pressing being about 150 combination with one of the weak acids, such,
sheets are applied to the cellulose plastic sheet,
pounds per square inch, and the temperature being about 240 degrees F.
Other examples of the cement found sa factory are as follows:
. Grams Sodium borate or perborate 1.0 Saturated solution silicic acid 0.25 E20 100 Grams Boric acid H 0.25 10 Saturated solutionstannic acid. 0,25 H2O 100 Grams Potassium tetraborate Saturated solution chroniic acid 0.25 H2O 100,
Grams Boric acid 0.25 Saturated solution arsenic acid 0.25 H20 100 The invention contemplates the combination of two or more of the weak acids, or two ormore of the boron compounds, although there is no practical advantage in suchcombination.
Whatweclaimis:
1. A method 0! compositing a sheet of cellulose plastic and a glass'sheet which comprises the step of coating the face of the glass sheet with a solution of a boron compound and one of the weak acids of the group consisting of silicic acid, stannic acid, chromic acid and arsenic-acid,- assembling the sheets and applying'heatand pres sure.
2. A method of compositing a sheet of. cellulose plastic and a glass sheet which comprises the step of coating the face of the glass sheet withplasticand a glass sheet which comprises the 1 step or coating the face of the glass sheet with a solution or a sodium borate compound and one of the weak acids of the group consisting of silicic 7 acid, stannic acid, chromic acid and arsenic acid, assembling the sheets and app y heat and 7 pressure. I
4. A laminated plate comprising a pair of glass sheets cemented to the opposite sides or a sheet at cellulose plastic with a cement comprisinga boron compound and one of the weak acids of the group consisting of silicic acid, stannic acid, A chromic acid and arsenic acid.
5. A laminated plate comprising a pair of glass sheets cemented to the opposite sides of a sheet of cellulose plastic with a cement comprising boric acid and one of the weak acids of the group 5 consisting of silicic acid, stannic acid, chromic acid and arsenic acid.
6. A laminated plate comprising a pair of glass sheets cemented to the opposite sides. of a sheet of cellulose plastic with a cement comprising a sodium borate compound and one of the weak acids of the group consisting" of silicic acid, stannic acid, chromic acid and arsenic acid.
